瑞士蘇黎世生活費全球最高

Recently the Mainichi News on-line reported the following:
生活費の高い都市を調べた調査で、スイスのチューリヒが、東京を抑えて１位になった。英経済誌エコノミストの調査部門エコノミスト・インテリジェンス・ユニット（ＥＩＵ）が、世界の１３０都市にわたり、食料や衣料、家賃など４００以上の価格を調べた。
　この調査によると、欧州債務危機を危惧する投資家が、ユーロからより安全なスイスフランに資金を移すなど、スイスフランの高騰が影響し、チューリヒは昨年の５位からトップに浮上した。ジュネーブは３位だった。
　オーストラリアは５都市がトップ２０入り。シドニーとメルボルンはそれぞれ７位と８位だった。調査を担当したジョン・コープステイク氏は「オーストラリアの生活費に最も影響しているのは為替レートで、過去１０年で豪ドルは対米ドルで２倍上昇した」と声明で語った。
　カナダのバンクーバーは３７位にランクインし、北米で最も生活費のかかる都市となった。米国ではロサンゼルスが一番高く、上海と並ぶ４２位。ニューヨークは４７位だった。
　アジアではシンガポールが９位に、韓国のソウルが２７位にランクアップした。

   Based on the investigation that looked for cities with high living expenses, Zurich in Switzerland exceeded Tokyo to rank first. The English economic magazine Economist's investigation section the Economist Intelligence Unit (EIU) spread out to 130 cities in the world to investigate the prices of 400 or more items, such as food, garments, and house rental.

   According to this investigation, the investor who was apprehensive about the Europe debt crisis had moved funds from Euro to the safer Swiss franc, thus led to the appreciation of the Swiss franc and affected Zurich to move up to the top place from the 5th place last year. Geneva was at the 3rd place.
In Australia five cites had move to the top 20. Sydney and Melbourne were at the 7th and the 8th place, respectively. Mr. John Koepp Stig who took charge of the investigation said in a declaration that "It is the exchange rate that has influenced the living expenses of Australia most, and the Australian dollar went up twice against the U.S. dollar in the past ten years".

   The rank of Vancouver in Canada ranked at the 37th place to become the city that had the highest living expenses in North America. In the US, Los Angeles was the highest at the 42nd place which was same as Shanghai. New York was at the 47th place.

   In Asia Singapore was ranked at the 9th place, and Seoul of South Korea had gone higher to the 27th place.

I am wondering why Hong Kong was not mentioned.
